Copper layer was plated on 100 um PET film as a substrate to enhance the electric properties for the material of electronic parts in a supercritical CO2 Plating System (SCPS). In SCPS, experiments were conducted in the range of 45~75℃ temperature, pH of 12.5, CuSO4•5H2O/NiSO4•6H2O=12.5 bath composition, SnCl2/PdCl2=16 activation composition, and the pressure of 7~17 Mpa, CO2/electrolyte (volume ratio) = 9 respectively. The optimized temperature on the copper plating was showed at about 45℃. The effect of pH, bath composition, reaction time on the copper plating in SCPS was investigated as well. The electric properties of Cu/PET film electroless plating technology in SCPS were higher than those in conventional method. |
